Model: CMP5000WXE - 50" PLASMA DISPLAY Condition: 1 Constantly Symptom: 31x Other 'no picture' problem Digital Noise only on Screen or Monitor will not start Tip: 1. Disconnect the 2 connectors from the Y drive PCB to the scan IC PCB's (Y3 and Y5). DO NOT POWER UP THE DISPLAY as this would cause even more damage 2. With a meter, measure the impedance between VH and GNDH on the connector on the scan IC PCB's (there are 2, for the upper and lower half of the display). The half with the faulty scan IC should indicate low impedance. 3. To find the actual IC, check the impedance between GNDH and each address line on each scan IC. On a faulty scan IC, this will be low impedance. Replace the faulty scan IC's as necessary IRIS Part: TC03151 IC SN755860PJ Section: IMG Image display unit Defect: Q Short Repair: A Replacement
